Rationale 1: Ortolani's maneuver is an assessment technique that rules out the possibility of congenital hip dysplasia.
Rationale 2: Babinski's reflex tests for upper neuron abnormalities.
Rationale 3: When the Moro reflex is elicited, the newborn straightens both arms and hands outward with the knees flexed, then slowly return the arms to the chest, as in an embrace. If this response is not elicited, the nurse assesses the clavicle. If the clavicle is fractured, the response is demonstrated on the unaffected side only.
Rationale 4: Trunk incurvation (Galant reflex) is seen when the newborn is prone and the pelvis is turned to the stimulated side when the spine is stroked.
